I bought a Lenovo legion Y545. And personally, it’s not good. Though the screen refresh rate says 144Hz. It feels like 60Hz. I have tried 144Hz before and it feels a world apart. And in settings, it says its 144Hz. Also, it is set to the intel graphics by default and I had to do many bios updates to fix that. The display at some point wouldnt even change brightness and all. The GPU in prev drivers used to make these white criss-cross patterns over the screen on GPU apps. The Display is really bad and you can see that it has huge bright spots when the screen is dim. The Laptop is generally decent during games but when charger isn’t plugged in it just decreases FPS. The CPU runs at more than 4 GHz on idle and GPU goes up to 90 degrees playing minecraft -_-. The Battery was told to last about 4-5 hours but all i see is just 30 mins. Honestly lenovo sucks. And this happens with all laptops my mom has a lenovo laptop also and it cant run google chrome properly.
